Do I have to reset all camera paramters if I change one [Android Camera Parameters]? -


i couldn't find information in android docs. here question:

when change 1 parameter of camera, have reset parameters have set before or can sure not affected call mcamera.setparameters(params)?

for instance, when update zoom value calling

params.setzoom(zoomvalue); mcamera.setparameters(params);

will things white balance or auto focus stay untouched? , if so, can sure case android devices?

thanks!

right, camera.setparameters() don't support defaults. that's why use following sequence:

camera.parameters params = mcamera.getparameters(); params.setzoom(zoomvalue); mcamera.setparameters(params);

often, people try avoid multiple calls getparameters() using member:

private camera.parameters mparams;  ...  mcamera = camera.open(); mparams = mcamera.getparameters();  ...  params.setzoom(zoomvalue); mcamera.setparameters(params);

but there 1 catch: result of setparameters(), seemingly unrelated parameters may change; next time, if use same mparams, may effect result (the examples entirely specific combination of hardware , system). therefore recommend not use cached camera parameters.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
